The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

BEST KALI TOOL TO MAKE UNDETECTABLE BACKDOOR 2022?
syswhispers2 -- tool for helping unhook userland hooks by reimplementing syscalls. Basically just generates a header file; you still have to write the loader yourself.

Are the logs from all .evtx and .etl files included with Get-EventLog and Get-WinEvent?
Yes, and based on this table sysmon actually causes additional events to be generated (although I think it is hooking high level APIs, so I think a technique like SysWhispers might cause some of these events to be invisible through Sysmon) so that could be useful even if we're not focused on the GUI. Writing my own ETW consumer / providers is a little advanced for me right now, so that's cool.

Can't do exploitation research on a novel unhooking approach without a database of the DLLs for every Windows version. Ideas?

Obfuscating powershell beacons
If you wanna stay with unmanaged code look into https://github.com/jthuraisamy/SysWhispers2 I'm a noob with native languages so can't say how effective it is. It also has a downside including ASM references to the binary that are unusual and might be detected, not sure on this tho.

Can't do exploitation research on a novel unhooking approach without a database of the DLLs for every Windows version. Ideas?
I wrote about some weaknesses (this explains what this post is all about) I saw in this approach and reached out the the author of that 2017 Cylance whitepaper, Jeff Tang, who responded:
-
Is there any public database I can get a copy of every Windows release at?
Some context: I'm testing a form of unhooking which involves replacing the dynamically linked copies of DLLs with fresh, unhooked versions. I lay out reasons an attacker might not want to use Cylance's approach (linked above), primarily that it involves trusting the defender's copy of the DLL on disk.
What are some alternatives?
